Impact of Frailty on the Development of Proximal Junctional Failure

Spine, 2023
Background. Patients undergoing surgery for adult spinal deformity (ASD) are often elderly, frail, and at elevated risk of adverse events perioperatively, with proximal junctional failure (PJF) occurring relatively frequently. Currently, the specific role of frailty in potentiating this outcome is poorly defined.

Diagnosis and Classification of Proximal Junctional Kyphosis and Proximal Junctional Failure

2017
Technical advancements have allowed the spinal deformity surgeon to achieve newfound abilities to correct severe spinal malalignment. However, proximal adjacent segment pathology (ASP) remains a significant issue. Examples include proximal junctional kyphosis (PJK) and proximal junctional failure (PJF).

Neurological Comorbidities Predict Proximal Junctional Failure in Adult Spinal Deformity

The Spine Journal, 2017
Retrospective case-control matched cohort from a single institution.To examine the contribution of nonmechanical factors to the incidence of proximal junctional failure (PJF) after adult spinal deformity (ASD) surgery.Multiple studies have reported on the prevalence of PJF following surgery for ASD.

The Evaluation, Prevention, and Management of Proximal Junctional Kyphosis and Failure

Journal of the American Academy of Orthopaedic Surgeons
Proximal junctional kyphosis (PJK) occurs commonly after surgery for adult spinal deformity. PJK exists on a spectrum, from a pure radiographic diagnosis to those patients with more severe deformity leading to notable pain, morbidity, and neurologic compromise requiring revision surgery—often described as proximal junctional failure (PJF).

Revision surgery for proximal junctional failure: A single-center analysis

Clinical Neurology and Neurosurgery
Proximal junctional kyphosis (PJK) is a radiographic complication following adult spinal deformity (ASD) surgery due to degeneration of mobile segments adjacent to fused spine. Proximal junctional failure (PJF) represents PJK with structural failure, neurologic deficit, or mechanical instability warranting revision with extension of fusion above the ...

Prevention of Proximal Junctional Kyphosis or Failure: Cement Augmentation

Techniques in Orthopaedics, 2020
Vertebral cement augmentation (vertebroplasty) has recently garnered increasing attention as a possible prophylactic treatment for the prevention of proximal junctional kyphosis and proximal junctional failure in osteoporotic patients undergoing long spinal fusions.

Preoperative alignment and risk of proximal junctional failure

The Bone & Joint Journal
Aims Proximal junctional kyphosis (PJK) remains a major complication after surgery for adult spinal deformity (ASD). While postoperative alignment is a recognized modifiable risk factor, objective methods for selecting the upper instrumented vertebra (UIV), a key modifiable factor, are lacking.
